LightWare SF20/HA 100m
LightWare SF20/HA is an ultra-lightweight 100 m LiDAR rangefinder designed for high-accuracy distance measurement in UAVs, robotics and other compact sensing systems.
About This Product
The SF20/HA combines a compact form factor with high-accuracy laser distance measurement. It can measure distances up to 100 metres and is designed to maintain sub-centimetre accuracy across its operating range under specified conditions. Its onboard servo driver also allows beam-steering applications when used with suitable mounting hardware, making it useful for advanced sensing and mapping setups.
